Hey ladies could someone help with advise on this

I’m just over 7 weeks pregnant (this isn’t my first) but I never experienced this in my last one.. I shaved my legs the other day with razor and foam ( I ain’t done this in months as I hve used an electric one) but from I have done so my legs have been going mad with itch like non stop, to the point of scratching so much I have cut my legs and left scratch marks?

Any advice on this would be amazing!
